We keep it at 80 to 95db, I concider 80db exceptable for loud. Pipe organs can get very loud, but sound sweet. Outside of the world of church music, I've recorded drums in a old traditional church. Granted there was no one there, the room just sounded awesome with the natural ambiance of the room. I know in that case drums would be over kill, but we used it for a different reason.I understand but these churches must be full of young people. The older folks would cringe to listen to loud music. What we call medium volume they would call stadium volume. And most churhes I have been in have these high vaulted ceilings which would be terrible for sound. I sang in the choir in senior high and we had no mics. We sang at a volume that all could hear even in the back row. So unless you are playing in the Crystal Cathedral, why would you need electric guitars anyway?
